Crate box_self

Source
Expand description

Easy way to duplicate a new function with self: Box<Self> signature.

Sometimes you need both functions fn consume(self) and fn consume_boxed(self: Box<Self>). This macro generates the second one for you.

§Examples

   use box_self::box_self; 

   trait Animal {
       fn consume(self);
       fn consume_boxed(self: Box<Self>);
   } 

   struct Dog{}
   impl Animal for Dog{
       #[box_self(_boxed)]
       fn consume(self) {
           println!("Bark");
       }
   } 

   struct Cat{}
   impl Animal for Cat{
       #[box_self(_boxed)]
       fn consume(self) {
           println!("Jump");
       }
   } 

   fn main(){
       let animals:Vec<Box<dyn Animal>>=
            vec![Box::new(Dog{}), Box::new(Cat{})];
        
       for anim in animals{
           anim.consume_boxed();
       }
   }
